Hi Melek!
I can’t tell you about Stavanger (I haven’t been there), but I can tell you a little bit about Norway in general (I went there twice already).
In the middle of October, you will need a lot of warm clothes. I went there in June/July, but even then there were many rainy and cold days, so I needed a warm jacket.
You won’t have problems communicating with people because almost everybody there speaks English.
